Officials said they expected the death toll – already at 78 – to rise further after Tuesday’s explosion, as rescuers dug rubble to save people and remove the dead.
Images of the blast shared by residents on social media showed a column of smoke rising from the harbor followed by a huge explosion, sending a white cloud and fireball into the sky.
The victims were reportedly taken out of town for treatment because hospitals in Beirut were filled with wounded.
At least 4,000 were injured in the blast.
While people were warned to stay indoors due to the risk of toxic fumes.
Hours after the explosion, which struck shortly after 6 p.m., a fire still broke out in the port area, casting an orange glow across the night sky as helicopters hovered and ambulance sirens sounded in the capital .
The Lebanese government said it was still struggling to establish the scale of the disaster.
President Michel Aoun said 2,750 tonnes of ammonium nitrate had been stored for six years at the port without security measures and said it was “unacceptable”.
Officials did not say what caused the initial fire that set off the explosion. A security source and local media said he started with welding work done on a hole in the warehouse.
Survivors described the aftermath as the last days of the civil war.
